Test pp will have PIP like a mofo at 150-200. Any lab that has PIPless test pp 150-200...well its not 150-200. You can get away with 125/ml with minimal pip. So, yes if you wanna dose that high phenyl prop ester your gonna need EO..I would do it all in EO or 50/50. TBH, I dose my 100mg Test PP at 110mg per ml and its the smoothest shit since creamy peanut butter! I use 2/20 in safflower or GSO. Now...if you do go 150...put your solvents in first...gently heat them up....then add in all of powder...use glass stir rod and stir trying to dissolve all particles....now...gently reheat the solution for afew minutes.....and then restir and you will see all the particles completely dissolve...ahhhh....now add in maybe 50 percent of your oil carrier...reheat mix.....then add in the other half...reheat and mix again...there you go..perfectly blended and dissolved .....now filter through .22u and ba bam...beautiful light golden oil.....enjoy. I advise dosing at 110mg...its my fav ester for test and is super smooth when brewed "the long way" like I mentioned above...use solvents first....after all particles are fully dissolved add in oil...you could add in all oil at once tbh....but I like slow cooking my ribs if you catch my drift!
also don't heat to high...remember we are just mixing, we don't need to induce a chemical reaction (which in this case would be destroying some hormone) just enough to get it to properly dissolve...if you see small black particle in middle bottom of beaker/flask...burnt hormone
